Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Cream Puffs
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux dough
Combine butter and boiling water in a saucepan. Stir over heat until melted.
Add flour and baking powder, stirring until the mixture pulls away from the pan.
Remove from heat and let cool. Once cool, beat in eggs one at a time.
Bake the puffs
Drop spoonfuls of the mixture onto buttered baking sheets, dipping the spoon in cold water each time.
Bake in a preheated oven at 350°F (175°C) for about 45 minutes.
Make the custard and fill
Combine milk, egg yolks, sugar, and flour or cornstarch in a saucepan.
Add vanilla and cook over medium heat until thickened into a custard.
Once the puffs are cool, fill them with the custard.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts into the water to add richness and tenderness to the dough.
- All-purpose flour
- Starch and gluten give the dough structure to hold its shape around the steam.
- Eggs
- Bind the dough and set during baking, giving the puffs their structure and rise.
- Milk
- Forms the liquid base of the custard, adding creaminess and body.
- Egg yolks
- Thicken the custard as they set and add richness.
- Sugar
- Sweetens the custard and balances the flavor.
The step that matters
Baking the puffs until they are fully set. The steam from the wet dough inflates the puffs, and the starch and egg proteins must set before they collapse. Underbaked puffs can deflate as they cool.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, flour, egg, milk, sugar):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, flour, egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
